The ISSP evolved out of pre-existing general social surveys. Its origin was a bilateral collaboration between the respective national studies of National Opinion Research Center (NORC), University of Chicago and Zentrum fuer Umfragen, Methoden, und Analysen (ZUMA, now part of GESIS-Leibniz Institute of the Social Sciences), in Mannheim, Germany. Both institutes started to collaborate in 1982, devoting a small segment of their national surveys ALLBUS and GSS to a common set of questions.
In 1983, SCPR London (now National Centre for Social Research, NATCEN) started a social indicators series called the British Social Attitudes Survey (BSA) similar to the ALLBUS and GSS and initiated meetings to further international collaboration. As a result, representatives from NORC, ZUMA, SCPR and the Research School of Social Sciences, Australian National University organized ISSP in 1984. They agreed to:
- jointly develop topical modules dealing with important areas of social science,
- field the modules as a (fifteen-minutes) supplement to the regular national surveys (or a special survey if necessary),
- include an extensive common core of background variables,
- make the data available to the social science community as soon as possible.
Funds and Archives
Each research organisation funds all of its own costs. There are no central funds to run national ISSP surveys or fund organisational or methodological tasks.
